Summary

From 2011-2018 USGS biologists recorded vegetation and biological soil crust (BSC) cover by species and tracked survival of tagged individual plants (388 in total) across 40 locations where paired experimental plots had been installed in 2010. Plant cover was visually estimated using four 75 x 100 cm survey frames. Each site contained a two plots measuring 1.5 by 2.0 meteres: a control plot and a plot covered by a shelter that excluded 35% of incoming precipitation. Plots were selected to represent shallow vs. deep soils, sandstone vs. shale parent material, and dominant plant species on the Colorado Plateau around Moab, Utah. We used an information theoretic approach using generalized linear models to determine the combination of [...]

Purpose

The purpose of these data are to understand the vulnerability of common native species of the Colorado Plateau to increased aridity. Specifically, these data can be used to forecast which species will be most vulnerable to drought-induced mortality and how vulnerability is exacerbated by the presence of invasive species. Nearly 400 individual plants were tracked throughout the duration of the experiment and mortality data were evaluated in the context of the relative contribution of treatments, interannual-climate variability, and species identity to determine drought-susceptibility in these dryland systems. The importance of multiple abiotic and biotic factors in driving responses to drought can also be tested, including elevation, soil depth, and parent material, as well as biotic interactions with biocrusts and invasive species.
